Ring size guide

Lay a ring you own flat on the circle and slide until it sits just inside it — or set its inner diameter directly.

Measure the inside of a ring that already fits — inner edge to edge — with a ruler in mm, then set it below. No ring handy? Try Measure your finger.

Between sizes? Always choose the larger size. Fingers are slightly bigger in the evening — measure then for the best fit.

Method 1 — Use an existing ring

Find a ring that fits the intended finger comfortably.
Place it flat and measure the inner diameter (inside edge to inside edge) in mm.
Enter that measurement in the Measure a ring tab.

Method 2 — Wrap and measure

Wrap a thin strip of paper around the base of your finger.
Mark where it overlaps — measure that length in mm (your circumference).
Divide by 3.1416 (π) to get your diameter, then use the Measure a ring tab.

Tip: Middle finger sizes typically run half a size larger than the ring finger. If between sizes, go up. Measure in the evening — fingers are slightly larger then.

This cushion lab grown diamond halo engagement ring is designed for someone who loves brilliance from every angle. At the center, a cushion-cut diamond is framed by a sparkling halo that amplifies its presence while preserving the soft, romantic outline that makes this shape so loved.

The split shank creates an airy, architectural profile, drawing the eye toward the center stone while adding extra sparkle through hand-set accent diamonds along both shoulders. The result is a ring that feels substantial, bright, and beautifully balanced on the hand.

Made to order in your choice of center size and metal, this design combines classic halo styling with modern customization so the finished ring feels uniquely yours.

About Lab Grown Diamonds

A cushion's pillow outline and rounded corners give a softer, warmer glow, with larger facets that scatter light in broad flashes. It pairs naturally with vintage, halo, and double-halo designs and wears gently against the skin.

Every Signora Jewels diamond is grown in a controlled lab using the CVD process, producing a stone that is chemically, optically, and physically identical to a mined diamond — same hardness, same fire, graded on the same 4C scale. Because the supply chain is short and traceable, you get a larger, cleaner stone for the same budget and a documented origin, with no mining footprint. The result is a diamond that looks and tests exactly as a natural one, with more carat and clarity for your money.

FAQ

Can I change the center stone size?
Yes. Center sizes from 1 CT to 4.5 CT are available, and the setting is scaled to suit the stone you choose.

Are lab grown diamonds real diamonds?
Yes. Lab grown diamonds are chemically, physically, and optically identical to mined diamonds and are graded on the same 4C scale.

Will the halo and side stones stay the same?
Yes. The halo and accent diamond design remains part of the ring and is included as shown.

What metals can I choose?
Silver, 9K / 14K / 18K gold in yellow, white, or rose, and Platinum.

Is this ring made to order?
Yes. Every ring is crafted to order according to the center size and metal option you select.
